Rear coil spring problem

Is there something that hold the rear coil springs in place other than the wieght of my 03 AV 1500 Z71 4x4? Like a retainment bolt or something. I was lazy one time and had Walmart change the oil and both coil springs fell out to the side and was rubbing on the frame. Thanks for any help

I have been searching for answers and ran across that link too. I did put new shocks and asked the sales rep specifically if these fit a stock truck. I put on some Skyjacker 8000. Cause I do some light off roading hunting and stuff and thought those would do good for what I do. I spoke to my local after market parts supplier and he said he thought they should have a bolt or bracket in the top of the coil springs to hold them in place

Like RayVoy says the springs are basically held in the spring bucket by the weight of the truck. Suburbans have issues with sagging springs after a while as they get compressed and begin to collapse.
Along with that SkyJacker 8000 shocks for a stock height truck are also the same shocks used on a truck with up to 2" lift that means they have slighly more travel than stock shocks which will allow the axle to drop a little more between those two things that could be why your springs fell out.
To prevent this you could fabricate or purchase a set of limiting straps for your axle.

Thanks for the info. I am the second owner and I believe the previous owner did a fair amount of hauling. I got it at 100k miles do you thing that the spring may have collapsed? But I didn't have any problems till after the shock install. I am about to have some new tires put on in the next few weeks. This is why I am trying to figure out what is the best thing to do

Its a ten yr old truck so Id expect the springs to have lost some of their height not exactly a total collapse but enough that with slighly longer shocks you have this problem.
take a look at the rear bump stops if the springs arent holding up as well as they should you should see siggns on them where youve been bottoming out.

Yea youve been chewing up those bump stops.
Time to start looking at coil replacements.

Do you happen to have any suggestions? I found some MOOG replacements. And do I only need the coil insulators or do I need both the insulators and coil seats? On the diagram I found it only shows coil insulators. But at Rockauto.com it shows both listed for my truck. Thanks for all your help

Do they have pictures with the parts?
The insulators are normally a rubber pad or bushing the coil sits on to insulate it from rubbing directly on the coil seat or bucket.
The seat is normally what the coil sits in to stay in place.
I dont see you mentioning the actual coil itself.
